An integration design of compact E‐plane multiway waveguide power dividers

Abstract

SUMMARYIn this paper, E-plane multiway waveguide power dividers consisting of many steps, many sections, and corners are treated. Practical dividers with a small size and a broad bandwidth are designed. In general, in a structure with various discontinuities placed close together, it is necessary to take into account the mutual interactions among the propagating and nonpropagating modes. The design method based on the E-plane planar circuit approach and the segmentation/desegmentation method used in this paper can provide accurate circuit characteristics with simple matrix calculations. Therefore, optimal design of a circuit configuration consisting of several discontinuities can be performed within a short time. First, the trifurcated and tetrafurcated dividers for the X band are designed. Next, an integrated design is attempted for three-and fourway dividers with mitered bends at the output ports. As a result, flat power dividing characteristics over the entire X-band are obtained. The validity of the present design method is confirmed by means of an electromagnetic field simulator (HFSS) and trial experiments.
